In this paper, we used a thin polycarbonate (PC) chamber to improve the performance of an electrowetting lenticular lens array. The polycarbonate chamber changed the radius of curvature (ROC) of the oil acting as a lens, which increased the dioptric power of the liquid lens to 1666.7D. The increase in dioptric power required a reduction in the distance between the optical center of the lens and the display pixels under the chamber, which was accomplished by reducing the thickness of the chamber. The optimal thickness of the chamber was determined to be 0.5mm. Using this thin PC chamber, transmittance and viewing angle were measured and compared with an electrowetting lenticular lens with a conventional 1mm poly methyl methacrylate (PMMA) chamber was done. Crosstalk which degrades clear 3D images, is an inevitable factor in lenticular lens type multi-view systems. With the 0.5mm PC chamber, the viewing zone was expanded and the ratio of the crosstalk area was reduced, which resulted in a clear 3D image. The new method of depositing the electrode layer also ensured the uniform operation of the liquid lens array.
在本文中,我们使用了一个薄聚碳酸酯(PC)腔室来改善电润湿双凸透镜阵列的性能。聚碳酸酯腔室改变了用作透镜的油的曲率半径(ROC),这将液体透镜的屈光力提高到了1666.7D。屈光力的增加需要减小透镜光学中心与腔室下方显示像素之间的距离,这通过减小腔室厚度来实现。确定腔室的最佳厚度为0.5mm。使用这个薄PC腔室,测量了透过率和视角,并与具有传统1mm聚甲基丙烯酸甲酯(PMMA)腔室的电润湿双凸透镜进行了比较。串扰会降低清晰的3D图像质量,是双凸透镜型多视图系统中不可避免的因素。使用0.5mm的PC腔室,观察区域得到了扩展,串扰区域的比例降低,从而得到了清晰的3D图像。沉积电极层的新方法也确保了液体透镜阵列的均匀操作。
